SHADE OR REFLECTOR.

Application filed February 12, 1910. $e1ia1 .No. 543,323.

To all wiwm it may concern:

and render the reflected rays less strong and penetrating.

A further object is to provide a glass shade or reflector wherein thereflecting.

prisms have outer plain facets, giving said prisms a truncated formadapted for permitting the passage of light rays in radial directions.rind a still further object is to provide a reflector having outerfacets on the reflecting prisms, adapting it for trans mitting, a Wellas for reflecting, light, and having on said facets bead-likeprojections each of which is adapted for concentrating iight rays at apoint outside'the reflector, said projections consequently giving to thereflector a highly ornamental appearance.

in describing the invention in detail, reference is had to theaccompanying drawing, forming a part of this specification, in whichFigure l'is a side elevatibn of a shade or reflector embodying myinvention; F ig. 2 is a vertical section on the line 22, Fig. 1; andFig. 3 is a horizontal section on the line 33, Fig. 2.

Referring to said drawing, in which like designating charactersdistinguish like parts throughout the several views-1' indicates thebody of the glass shade or reflector, which may be of any preferred formand which is i'urrowed on its exterior with V-shapcd substantiallyparallel grooves 2, 't'orming prisms Be it known that I, GEORGE L.KRAATZ, a l

jections 5, l

3 of truncated shape between adjacent grooves, each prism terminating ina longitudinal facet 4, parallel to its base, instead of in the usualedge.

Formed on the facets 4 and spaced apart In any preferred manner arebead-like proeach of which constitutes an extremely small plano-eonvexlens of a bullseye type adapted for concentrating light rays. As isobvious, the facets i permit the transmission of light rays which wouldotherwise, were complete prisms employed, be reflected; and theemployment of a large number of the bead-like, or lens-like, proections5, while ornamenting the shade or reflector, serves to concentratev someof the light rays and to so direct them that a soft, diffused and,'atthe same time, strong light will be directed radially.

Having thus described my invention, what I claim .as new, and desire tosecure by Letters Patent, isv 1, A glass reflector having its exteriorface fHIIOWBd with substantially parallel V-shaped grooves which areseparated so as to leave longitudinal plain surtacestherebetween, andbead-like projections formed on said plain surfaces.

2. A glass reflector having its exterior surface tun-owed withsubstantially parallel ii-shaped grooves, prism-like ribs occupying thespaces between adjacent grooves, said ribs terminating in outer lonitudinal facets, and bead-like projections ormed on said facet-s. i

3. A glass reflector of the prismatic type wherein the prisms terminatein plain narrow facets which lie parallel to their bases, andplane-convex lens-like project-ions formed on said facets.

In testimony whereof I aflix my signature ll. 16. DUNLAP, liuugn Monms.
